ecobee thermostats require a C (popular) wire to power on. In the event the current thermoregulator utilizes just two cables (R and W, or T and T), you can find an installation that is few available, based on the application.
Before starting, take note the annotated following:
You’ll not manage to install the Power Extender Kit (PEK) with heat-only 2-wire systems. The PEK can just only be utilized on furnace or temperature pump systems that do not have C cable вЂ” it is because the PEK calls for R (energy), G (fan), and Y (compressor) cables to work, and these 2-wire systems that are heat-only n’t have these G and Y cables
To find out compatibility, you will want to access both the wiring at your thermoregulator plus the wiring at your home heating where in fact the thermoregulator wiring concludes.
You can reach out to ecobee support for guidance, or hire a technician to aid in installation if you are not comfortable doing so
STEP 1:DETERMINE EXACTLY HOW MANY THERMOSTATS YOU HAVE CONTROLLING YOUR HEATING SYSTEM
For those who have one thermostat managing your heating system, continue to step two below.
Action 2:Determine how many additional cables you have actually behind your wall surface in the thermoregulator
Eliminate your thermoregulator from the wall surface to see any unused cables which are perhaps not presently attached to your thermoregulator. Make sure to always check behind the wall during the thermostat also.
